Abstract: In condensed matter physics, we all are interested in the physical properties of materials, and seek to understand physics therein. In general, we traverse a series of individual samples with systematic variation of interest (e.g., composition, defect concentration or thickness of a specific layer in layered system) on purposes, for example, 1) to see the trend of physical parameters according to the intentional variation, 2) to optimize a specific property or 3) to paint a picture of phase diagram. However, the limited number of samples sometimes renders it challenging to chase a true trend curve or to catch a subtle point, and the effect of inevitable unintentional variation across individual samples cannot be completely ruled out. In this talk, I will introduce combinatorial approach, which is a way to overcome the problems and puzzling situation mentioned above and thus accelerate the discovery of exotic physics and functional materials. I will show some example of studies with the combinatorial approach, including the observation of perfect Andreev reflection in the topological superconducting state as the manifestation of Klein paradox.
